Accessibility remote control for the blind
A remotely controlled device receives a first command from a remote control (RC) but does not execute the command. Instead, the remotely controlled device waits to receive the first command within a threshold period, and if not received twice within the period, the first command is then executed. However, the first command is not executed if it is received twice, at which point the name of the corresponding RC key is announced. A second double command caused by a second double press of the same key on the RC causes the remotely controlled device to announce the function of the key. The logic may be executed in the RC as well as or in lieu of executing it in the remotely controlled device.
1. A system comprising:
a display device (DD) configured to receive wireless commands from a remote control (RC);
at least one circuitry in the DD configured to:
receive from the RC a first command but not execute the first command;
responsive to the first command, commence a time period;
responsive to not receiving the first command a second time within the time period, execute the command; and
responsive to receiving the first command the second time within the time period, not execute the command and present information pertaining to a first key on the RC associated with the first command.
2. The system of claim 1 , wherein the circuitry is configured to:
responsive to receiving the first command the second time within the time period, not execute the command and present information pertaining to the first key on the RC associated with the first command, the information comprising a name of the first key.
3. The system of claim 1 , wherein the circuitry is configured to:
responsive to receiving the first command at least a third time, present enhanced information pertaining to the first key on the RC associated with the first command, the enhanced information comprising a function of the first key.
4. The system of claim 1 , wherein the circuitry is configured for playing the information on the at least one speaker of the DD.
5. The system of claim 1 , wherein the circuitry is configured for configuring the DD in a training mode responsive to receiving a command caused by selection of a special key on the RC, the training mode being associated with presenting the information associated with the first key.
6. The system of claim 1 , wherein the circuitry is configured for configuring the DD in a training mode responsive to selection of plural keys on the RC, the training mode being associated with presenting the information associated with the first key.
7. The system of claim 1 , comprising the RC.
8. A system comprising:
a remote control (RC) with plural keys selectable to cause the RC to send respective wireless commands from a wireless transceiver of the RC to a display device (DD);
circuitry in the RC configured to:
receive a selection of a first key;
responsive to receiving the selection of the first key, commence a time period but not transmit to the DD a command associated with the first key;
responsive to not receiving a second selection of the first key within the time period, transmit to the DD a command associated with the first key; and
responsive to receiving the second selection of the first key within the time period, present information pertaining to the first key.
9. The system of claim 8 , wherein the circuitry is configured for playing the information on at least one speaker of the RC.
10. The system of claim 8 , wherein the circuitry is configured for causing the DD to play the information on at least one speaker of the DD.
11. The system of claim 8 , wherein the circuitry is configured for configuring the RC in a training mode responsive to receiving a command caused by selection of a special key on the RC, the training mode being associated with presenting the information associated with the first key.
12. The system of claim 8 , wherein the circuitry is configured for configuring the RC in a training mode responsive to selection of plural keys on the RC, the training mode being associated with presenting the information associated with the first key.
13. The system of claim 8 , wherein the circuitry is configured for:
responsive to receiving the second selection of the first key within the time period, not execute the first command and present information pertaining to the first key, the information comprising a name of the first key.
14. The system of claim 8 , wherein the circuitry is configured to:
responsive to receiving at least a third selection of the first key, present enhanced information pertaining to the first key, the enhanced information comprising a function of the first key.
15. The system of claim 8 , comprising the DD.
